What i have noticed while i am currently benchmarking these is how much more smooth they are over my 6970s. For example in unigine heaven on my 6970s when the framerate would dip low i would notice a lot of microstutter. While on the 7970s at low fps there is no noticable micro stutter at all. Very impressive.

7970 has great Tess. Performance compared to 6970 where 5870 was terrible there.
